rsh issued, no response received

[dsdoubt]

I have alredy set up SSH for Server1 and Server2 from Engine node. Iam able to do the SSH for the servers manaully. Where as not run the jobs from Datastage. Which gives me Section Leader died error.
Server1 is a ETL resourse node, Server2 is a Database server.
The ID used is part of dstage group.
Other jobs are running in the project with the same id, which does not access that particular database.

I get the follwoing error, when I do the configuration Check.

Code: Select all

##I TOCK 000000 11:56:49(001) <main_program> OS charset: 
ISO-8859-1.

##E TFPM 000356 11:57:22(002) <main_program> 

**** Parallel startup failed ****

This is usually due to a configuration error, such as
not having the Orchestrate install directory properly
mounted on all nodes, rsh permissions not correctly
set (via /etc/hosts.equiv or .rhosts), or running from
a directory that is not mounted on all nodes. Look for
error messages in the preceding output.

Hi,

Can you please issue the below commands and share your output along with the configuration file contents that you are using.
From server1
a. ssh dsusername@server2
b. ping server2

Also let me know the uid/gid of the dsuser in both the machines.

Cheers!

Chanaka

have you done this step?

On the primary computer, create the remsh file in the /Server/PXEngine/etc/ directory with the following content.
#!/bin/sh
exec /usr/bin/ssh "$@"

You should also look to the quality of your SSH keys.

What I mean by that is: Are the SSH keys created based upon the shortname of the server or the fully qualified name?

If you are using the dynamic_grid.sh script it populates the dynamic host name with a fully qualified version.

Go peek at /etc/ssh2/hostnames to see your SSH keys (probably the correct path, not sure on your system).

Has your server2 system ever worked in your setup?

Are you credentially mapped to a given user id? Have you executed your SSH tests using that id or your own?

SSH keys are a two part combo. Did you make sure that on your Conductor server you have both keys for Server1 and Server2, and on Server1 you have the key in the user id path for Conductor node, and the same for Server2?
